In historical numeral systems

Egyptian

1 lotus, 7 coils of rope, 4 hobbles, 8 strokes

1 × 1,000 + 7 × 100 + 4 × 10 + 8 × 1 = 1,748. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 9 vertical wedges (sixties place), 8 vertical wedges (units place)

29 × 60 + 8 = 1748. Places are separated by a space on the tablet, with the higher place written first.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
